Renewed December 29, -1933 `6 Claims.

The present invention relates toa combined tool, andparticularly to a novel holdergconstruction characterized in that it is capable of removably receiving a reversible toolto present eith`er end of the same in'position for use. However, it is to be understoodA that theinvention is not to be restricted to use with reversible tools, as it is equally well adapted for use with interchangeable tools of different sizes or: characters'.

It is an object `of the invention to provide means for rigidly, but removably, interlocking various tools in a holder adapted for hand mation and quickly operable. y

A further object of the invention is to provide cam means for maintaining the tool inv operative position in the holder so as to preclude relative movement betweenthe tool and holder.

A still further object of the invention is to provide a tool holder which comprises few parts so as to minimize manufacturing costs,-said parts primarily consisting of.a handle member, a ferrule, and a tool socket member positioned within" the handle.

Other and further objects and advantages` of the inventionwill be hereinafter'set forth and the novel features thereof defined by the apl pended claims.

Like'reference characters refer to likeparts in theseveral figures of the -drawing in which A designates the tool holder generally while B indicates the combination or removable tool. 'Ihe tool holder A comprises a hollow handle member 1 closely surrounding the tool socket member -2.

The forward end" of the toolV socket member'is somewhat tapered as indicated at 3 to receive the tool retaining ferrul'e' member 4 as clearly seen in Figs. 1 'andof the drawing. The ferrulememberhsprovidedwithacamslotcm nipulation, said means being simple in construe? "(Cl. I`|.5)`

operating with'the projecting v pin 6' carried by thetool 4socket member 2. The ferrul/emember 4 is provided at 7 with an abutment flange, said ange having diametrically oppositeA notched portions 7a for purposes that will later be explained. 'I'he rear portion ofthe handle member .extendsslightly beyond the tool socket member as seen in Figs. 2.and 5 thus forming a circular recess into which the tool SuDDOrting member 8 is inserted. The tool socket member isprovided with a; central bore or recess 2a into which the.

rear portion of the tool Bis inserted. This recess `2a also is adapted toreceive the reduced shank of the Vtool supporting member 8. Cooperative ""relation between fthe handle. member, the tool socket member and the tool supporting member is effected by the pin or fastening member 9 which is riveted or otherwise segured in the handle member 1.

The tool 'supporting memberas seen lin detail in Figs. 2, 5 and 8 comprises a shank portion 10 having a central conicalA bore ll'and V-shaped notchA 12 extending-therefrom and is, of course,

apertured at '12 to receive the cross pin 9 before referred -to and is "provided with a ange or con centric head 13 which rests 'against the end of the tool socket member 2. -The forward end of 4this tool socket member is provided with tool engaging means in the form of transverse notches 14 to engage the tool. B to prevent rota-- tion thereof when positioned within the holder A. 1

' The t'ool Bas shown in the drawing comprises a central shankv portion 15 terminating `at one endin the screw driver bit 16. Qn theother end of the shank portion is formed van ice pick or gimlet 17. The shank portion is provided intermediate itsends with projections or laterally 'extend-i ing lugs 18 arranged tobe moved into operativel I relation with the tool engaging means or notches 14 inl the forward en d of the tool socket memberv 2. Referring to Fig.'2.o f the drawing it willbe observed that when the tool B is inserted in the toolhandle A' and the rotatable "tool, retaining ferrule 4 is shifted tothe' position shownl the cammlng slot 5 will' move the-ferrulefrearwardly and at the same time shift the position ofthe notches "la in the abutment flange outof align ment with' the lugs 18 on' the tool itself thus causing the abutment flange to engage'the ends of the lugs 18 and move .the tool rearwardly to- -wards the tool supporting member. The tapered portion 17 forming a supplemental tool when th'e tool is reversed. n ow rests in the :conical shaped recess 11 in the tool supporting member and firmly holds the tool in aligned position as clearly seenin the drawing. When it is desired to remove the tool from the holder* either to reverse the same or for the insertion of the new tool the ferrule member is rotated to the left, this manipulationcausing the pino to ensue the 1rol forwardly from the position shown in Fig. 2 of the drawing to the position shown in Fig. 6. As

` the pin 6 reaches the end of the slot 5 the notches 'Ia in the abutment ange '7 align with the transverse notches 14 in the tool socket member and at this time the engagement withthe ends of the lugs 15 on the tool is broken and the tool B j may be readily removed from the holder A.

tion being inserted in the tool socket member and the ice pick o'r gimlct dispose in operative .tool within the socket member against relative.-

position the screw driver bit portion is disposed in the V-shaped notches 12 thus firmly positioning the tool-in the handle, the notches 12 functioning in addition to the transverse notches 14 4 to prevent any rotation of the tool with respect to the handle. This arrangement is shown in dotted lines in Fig. 5.

While I have disclosed a tool of the reversible type I am not desirous of limiting my invention to this type of construction since the holder is applicable to various types of tools having a similar shank construction.

While the speciflcdetails of construction have been herein shown and described, the invention is not confined thereto as changes and alterations may be made without departing from the spirit thereof as defined by the appended claims.

Having thus described my invention, what I claikim as new and desire to secure by Letters Paten is: y

1. A tool holder comprising a handle member, a toolY socket member positioned within the handle member and rigidly connected thereto, said socket member having means for engaging a tool carried thereby tov prevent relative rotative movement of the socket member and tool, a ferrule associated with the handle member, and 'means cooperating` with the ferrule and with the socket member for releasably interlocking the tool withinsthe socket member against relative longitudinlmovement.

2. `A tool holder comprising a handle member, a tool socketmember positioned within the handle member and rigidly connected thereto, said socket member having means for -angaging a tool carried thereby to prevent relative rotative movement of the socket member and tool, a ferrule associated with the handle member, and
